摘要
在煤炭资源储量估算中,煤层风氧化带垂深都是根据煤质化验指标来确定,对在煤层底板等高线上如何确定煤层风氧化带宽度没有明确的规定,为此,依据实际工作中遇到的三种地质情况:地表基本平坦;地表有倾角且倾向与煤层倾向相同;地表有倾角且倾向与煤层倾向相反,分别用制图法、计算法确定其煤层风氧化带的宽度。
In coal resource and reserve estimation, vertical depth of weathering and oxidation zone is all determined by coal quality testing indices, hut no specific rules to determine width of weathering and oxidation zone on coal floor contour map. To this end, for three geological conditions： ground surface basically flattish; surface inclined and its dip same as coal seam dip; surface inclined and its dip reverse to coal seam dip, then use graphical method, numerical method to determine the width of zones respectively.
